DOUBLE-BARREL SING LE-TRIGGER FIREARM.

SPECIFICATION forming part of Letters Patent No. 608,046, dated July 26, 1898.

Application filed October 16,1897. Serial No. 655,423. (No model.)

To all whom it may concern.-

Be it known that we, HENRY WILLIAM HOL- LAND, residing at 28 Maida Vale, and THOMAS \VooDWARD, residing at 69 Ashburnham road, London, in the county of Middlesex, England, gun-makers, subjects of the Queen of Great Britain, have invented certain new and useful Improvements in Breech-Loading Small-Arms, of which the following is a specification.

This invention relates to double-barreled guns with a single trigger. In many of such guns the trigger acts on and raises a longitudinally-moving slide having lugs on either side so placed that when the slide is in one position the right-hand lug is beneath the right-hand sear, so that the right-hand barrel is discharged when the trigger is pulled, while when the slide is in its other position the left-hand lug is beneath the left-hand sear and the left-hand barrel is discharged when the trigger is pulled. Various devices have been proposed to prevent the premature discharge of the second barrel by the involuntary pull of the trigger caused by the recoil from first discharge; but there have been objections to all of these.

According to this invention we give to the slide an unusually long travel, so that the involuntary pull takes place before it has reached the position for firing the second barrel.

Figures 1, 2, and 3 are side elevations,partly in section, of the central portion of the mechanism, the two locks, one on either side of it,

being removed, but the positions of the sears of these locks being indicated. Figs. 4 and 5 are a plan and end elevation of the slide. Fig. 6 is a plan, the top being removed. Fig. 7 is a side elevation and section on the line 7 7 of Fig. 6. Fig. 8 is a rear elevation.

a is the slide. (Shown separately in plan and end elevation at Figs. 4: and 5.) The bridge-piece a rests on the top of the plate Z1, forming part of the trigger b. The nose b of the trigger projects up through the slot a and its pivot 1) works in the slot a 0 is a lever pivoted at 0, whose nose engages with the notch a in the slide.

a is a spring acting on the lever c and tending to cause it to draw the slide a forward.

a a are lugs on the sides of the slide a.

dis the safety-bolt, carrying a projection 02, which when the bolt is in the position shown in Fig. 1 comes above the nose 6 of the trigger and prevents the latter from being pulled.

d is alug on the bolt 01, which when the bolt is drawn back, as in Fig. 1, comes against the lever c and carries it and the slide a to their rearmost positions.

6 and f are the sear and the blocking-sear, respectively, of the right-hand lock, the remainder of which is not shown in Figs. 1, 2, and 3. The corresponding sears e f of the left-hand look, when in place, lie in the same transverse lines as these, as shown in Figs. 6 and 8.

The action is as follows: Opening the breech to reload carries the safety-bolt cl rearward and cooks both hammers g in the usual Way. The rearward movement of the bolt, as above explained, draws back the slide a, and the cocking depresses the sear f, which therefore descends in front of a small lug or projection a on the slide a, the parts being brought into the position shown in Fig. 1. The safety-bolt is then pushed forward, but the slide a is prevented from moving with it, as the lug a comes against the sear f. If the trigger be pulled, the right-hand barrel is now fired and the parts are brought to the positions shown in Fig. 2. When the trigger is released, the sear f remains in its raised position, and the lug a can therefore escape from it, and the slide a is free to move forward, so that the parts take the positions shown in Fig. 3, the

lug a being beneath the sears of the left-hand barrel, which is therefore fired when the trigger is again pulled.

Owing to the considerable distance through which the slide has to move the second or involuntary pull of the trigger caused by the recoil of the right-hand barrel takes place before it is possible for the slide a to have reached the position shown in Fig. 3.

It will be observed that the slide a is not retarded or impeded in its forward movement after the first barrel is fired. It will also be observed that the arm 0 multiplies the motion of the safety-bolt dthat is to say, the lower end of the arm 0 moves Very much farther or has a very much longer range of movement than the bolt d. Obviously the slide a might be connected with any other moving part of the lock to impart the desired movement; but it is always desirable that the movement of the part of the lock which gives motion to the slide should be multiplied by the connecting devices, so that the slide may have a relatively long movement when passing from its position for operating the first barrel to its position for operating the second barrel.

What we claim is 1. The combination of a single trigger, two sears, a freely-moving slide unretarded while moving from its position of firing the first barrel to its position while firing the second barrel, means for holding the slide in one extreme position when the gun is cooked and means for moving the slide after the first pull of the trigger and continuing this movement until after the involuntary pull on the trigger which occurs immediately after the first pull and before the second pull which fires the second barrel.

2. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears, a moving part of the lock and a connection interposed between such moving part of the lock and the slide, which multiplies the motion and gives to the slide an increased movement relatively to such moving part of the lock, and means for holding the slide in one extreme position when the gun is cooked, the arrangement being such that after the first pull of the trigger the slide is moved freely forward and continues to move until after the involuntary pull of the trigger, which occurs immediately after the first pull and before the second pull which fires the second barrel.

3. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears operating one sear when in one of its extreme positions and the other sear when in the other, means for holding the slide in one extreme position when the gun is cocked, an arm pivoted at the top of the lock and engaging with the slide and a spring acting on the arm.

4. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears operating one sear when in one of its extreme positions and the other sear when in the other, means for holding the slide in one extreme position when the gun is cooked, an arm pivoted at the top of the lock and engaging with the slide, a spring acting on the arm, and asafety-bolt adapted to move above the trigger and restrain its movement and carry the arm and slide to one extreme position.

5. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears operating one sear when in one of its extreme positions and the other sear when in the other, a lug on the slide, a blocking-sear engaging with the lug and holding the slide in one extreme position when the gun is cocked, and means tending to carry the slide to the other extreme position, the distance between the two extreme positions being such that the slide cannot pass from the one to the other in the interval between the first pull and the involuntary pull of the trigger.

6. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears operating one sear when in one of its extreme positions and the other sear when in the other, a lug on the slide, a blocking-sear engaging with the lug and holding the slide in one extreme position when the gun is cooked, an arm pivoted at the top of the lock and engaging with the slide and a spring acting on the arm.

'7. The combination of a single trigger, two sears, a slide interposed between the trigger and the sears operating one sear when in one of itsextreme positions and the other sear when in the other, a lug on the slide, a blocking-sear engaging with the lug and holding the slide in one extreme position when the gun is cooked, an arm pivoted at the top of the lock and engaging with the slide, a spring acting on the arm, and a safety-bolt adapted to move above the trigger and restrain its movement and carry the arm and slide to one extreme position.
